Python+Pygame怎么实现吃豆豆游戏

这篇文章主要介绍了Python+Pygame怎么实现吃豆豆游戏的相关知识，内容详细易懂，操作简单快捷，具有一定借鉴价值，相信大家阅读完这篇Python+Pygame怎么实现吃豆豆游戏文章都会有所收获，下面我们一起来看看吧。

一、首先

1）素材

首先找到吃豆豆游戏的界面按照上面的素材找找准备下相似的图片！如下：

2）环境

本文的环境都跟之前的差不多：Python3、Pycharm、Pygame模块。

模块安装：

pip install -i https://pypi.douban.com/simple/ pygame

二、正式开始

这款吃豆豆的小游戏：主要分为4块主要内容，分别是。Levels.py、Sprites.py、cfg.py、Game.py

1）配置文件：cfg.py

import os   '''定义一些颜色''' BLACK = (0, 0, 0) WHITE = (255, 255, 255) BLUE = (0, 0, 255) GREEN = (0, 255, 0) RED = (255, 0, 0) YELLOW = (255, 255, 0) PURPLE = (255, 0, 255) SKYBLUE = (0, 191, 255) '''游戏素材路径''' BGMPATH = os.path.join(os.getcwd(), 'resources/sounds/bg.mp3') ICONPATH = os.path.join(os.getcwd(), 'resources/images/icon.png') FONTPATH = os.path.join(os.getcwd(), 'resources/font/ALGER.TTF') HEROPATH = os.path.join(os.getcwd(), 'resources/images/pacman.png') BlinkyPATH = os.path.join(os.getcwd(), 'resources/images/Blinky.png') ClydePATH = os.path.join(os.getcwd(), 'resources/images/Clyde.png') InkyPATH = os.path.join(os.getcwd(), 'resources/images/Inky.png') PinkyPATH = os.path.join(os.getcwd(), 'resources/images/Pinky.png')

2）定义一些精灵类：Sprites.py
